I have updated to the latest firmware (1.15.23) using the wifi and usb. The setting show that 1.15.23 is installed, but the machine keeps insisting that there is a firmware update and wants to install 1.15.21. Not sure if this is related to my dual extruder’s inability to calibrate.
Mine does that too and I don’t have the dual extrusion module yet. It’s in the mail now though and unfortunately I’m not looking forward to it as much as I thought I would reading all these reviews.
I hope @Snapmaker-Support can help here.
I did OTA updates no problem up until latest.
